jr- ! Mr. K. A. Rusch Milprint, Incorporated 4200 N. Holton Street Milwaukee, Wisconsin 3200 Dear Ken: October 9, 1970 ' Just a note to advise you and the distribution of the status of the reproducibility problem at Milprint versus Philip Morris' pilot unit. First Results - Series of Planned Comparison Runs 1. All Philip Morris pilot plant runs (7) to date show the Controlled Profile. 2. Only one of the first six batch runs (yr76-8'1) at Milprint was within specifications (Run i , M) . 3. Previous hirM speed runs (150-175 ft./min.) r73-#75 also were not acceptable. From these results we conclude that your batch mixing is some how different than ours or the hardware difference, such as your dryer, has an effect on finished film versus our pilot operation. The series of runs not yet made into cigarets and smoked includes attempts to see effects of different drying conditions. In addition we have in progress experiments attempting to mix preparations that will not perform properly on our pilot plant if in fact a mixing-concentration phenomena takes place. Changed batch mix conditions at Milprint are also scheduled. It appears that the more uniform we have mixed, the poorer has become run performance.

Mr. K. A. Rusch October 9, 1970 R. A. Tamol Page 2. Market Test The Marketing Department has requested that a lower delivery Mark VII cigaret be developed and this work is in progress. The thought is to substitute the low delivery version in the test market. .Eitber:i latest good paper runs at Milprint (Run #59 or #77) would be used or our Philip Morris pilot plant production, until the commercial equipment problem is solved. Longer Term Program - Alternate Coating We are also investigating coating of an extracted WSRN 80 Polyox that uses a different s-olvent system and would require no peroxide. Bobbin life is unknown, but cigarets are ready for smoking immediately after making with this na terial. The pack temperature problem is not solved by this material, however. An alternate water insoluble material looks promising, but will require larger perforations. We are presently working in this area on our pilot equipment on a high priority basis. Printed Fast Burn Additive Milprint is assisting us by gravure pattern engraving pilot plant printing rolls and Mark VIII cigaret machine printin rolls to enable Philip Morris to reproduce the Hallmark cigaret ~Brown & Williamson Tobacco Company). Additional Solvent As per our discussion you will reorder Varsol as it is used in Polyox formulations. DCE will not be reordered and you will work from drum supplies as other solvents are being investigated. Let's hold on an ion exchange column to remove acidity from DCE as per Bob Roach's recent memo. As soon as we are in a position to ask you to investigate alternate coating materials we shall. Hopefully runs and experi- ments in progress will result in 3000 grade Polyox becoming commercial at Milprint. ~ /ad cc: Dr. R. B. Seligman,/ Mr. R. G. Armstrong Mr. R. N. Thomson Mr. F. V.
